gas ported 13:1 510 piston

Thinking about putting in one of these pistons,just wondering if anyone has used them before.The claim is an increase in power everywhere.I could live with that a little more everywhere would mean less fuel consumption,and shouldn't be that hard to tune with FI/mapping.Any comments would be greatly appreciated.

Boosting compression without changing cam timing will typically shift power to low-mid rpms at cost of high rpm.

What type of gas porting is done to the piston? Who is making the piston?

I'm not sure what that means maybe all the pistons are gas ported,that's just one of the features mentioned in this web add.http://www.ferracci.com/store/cart.php?m=product_detail&p=736
This site better explains and is what I was considering installing.

Scott Summers said his TXC 510 has more power than he could use so he had the compression lowered. Maybe GNCC is that type of riding.

can still use pump gas??

How will this affect the valve springs and bottom end with the added compression?
I thought the existing compression ratio was already high compared to most thumpers?
(Im no mechanic so excuse my ignorance)

any feedback?

I just talked with my service guy and he answered some of these questions.The pump gas issue,he said is not a problem.The reliability of the motor is not compromised in any way,and he has not had any problems,top or bottom end from the installation of these pistons.The pistons are machined not cast or forged,and are a direct "drop in replacement".They are sold at FBF,I'm contemplating pulling the trigger on one,since my motor is going down to the cases.I wonder if the MPG would increase due to more power.I guess you could pull taller gearing,I am basically doing dualsport/adventure and have even considered installing the counterbalancer to smooth out the engine.
